Growth Newsletter #298

December 4, 2025

At our ads agency, we pulled performance across a bunch of accounts. We just looked at one thing:

“How many distinct ad creatives did this account test
 and how well did it perform?”

And there was a really strong correlation:

  • Accounts testing LOTS of meaningfully different ads had better CPA, higher ROAS, more stable performance.
  • Accounts recycling the same 3–5 variations forever had chaotic results, random spikes, and fragile “winners” that died fast.

Meta’s Andromeda update basically hard-coded this reality into the platform. Targeting is commoditized and everyone’s running broad. Bidding is all automated and everyone’s on Advantage+.

The only edge you have left is creative.

(Ok, maybe not the only one, but one of the few).

Feed the system more distinct creative ideas and let it hunt for the perfect buyers.

Today’s newsletter is about what that actually means in practice:

  1. Why Andromeda rewards creative volume only if it’s meaningfully different
  2. The 3 neuroscience pillars of ads that actually work
  3. The anatomy of a high-performing ad: hooks, visuals, CTAs
  4. How to hold tension to win the click

Let’s get into it.
